According to the book, The Twentieth Century, the invention of typing correction fluid was the product of necessity.  Betty Nesmith (incidentally, the mother of former “Monkee” Michael Nesmith) had made so many typing mistakes she created a concoction that would cover the mistakes without smudging the paper.  She mixed the first batch herself and applied it with her eyebrow pencil.  She started mixing it for friends and eventually turned her enterprise into a 47 million dollar business.  When selling her Liquid Paper to Gillette, she negotiated a deal that gave her and her son royalties on each bottle sold until the end of the century.
